Just bought a giant bottle of Vitamin C from Costco with added "citrus bioflavonoids." They just couldn't settle for simple Ascorbic Acid.
Found this article:
Flavonoids are polyphenolic compounds of natural occurrence produced by plants that are largely consumed both for therapeutic purposes and as food. Experimental data have shown that many flavonoids could inhibit thyroperoxidase activity, decreasing thyroid hormones levels thus increasing TSH and causing goiter. In humans, infants fed with soy formula have been shown to develop goiter. However, in post-menopausal women soy intake did not affect thyroid function. In thyroid tumor cell line, flavonoids were shown to inhibit cell growth, but they can also decrease radioiodine uptake, that could reduce the efficacy of radioiodine therapy. Flavonoids could also affect the availability of thyroid hormones to target tissues, by inhibiting deiodinase activity or displacing T4 from transthyretin. Thus, flavonoids have been shown to interfere with many aspects of the thyroid hormones synthesis and availability in in vivo and in vitro models. In the present article, we review and synthesize the literature on the effects of flavonoids on thyroid and discuss the possible relevance of these effects for humans.
Should I use this Vitamin C?

Abstract
Experimental studies suggested that flavonoids may influence thyroid carcinogenesis, but epidemiological evidence is sparse. No study has examined different classes of flavonoids in relation to thyroid cancer risk. Using data from the NIH-AARP Diet and Health Study, which enrolled 491,840 U.S. men and women, ages 50 to 71 at baseline, we prospectively examined the risk of thyroid cancer in relation to dietary intakes of catechins, flavanones, flavonols, anthocyanidins, flavones, isoflavones, total flavonoids. Dietary intakes were assessed using a food frequency questionnaire. Cancer cases were ascertained by linkage to state cancer registries. Multivariable-adjusted Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs).During follow up (mean=9 years), we identified 586 thyroid cancer cases. Thyroid cancer risk was inversely associated with dietary flavan-3-ols (HRQ5 vs Q1 (95% CI): 0.70 (0.55, 0.91), p-trend=0.03), but positively associated with flavanones (HRQ5 vs Q1 (95% CI): 1.50 (1.14, 1.96), p-trend=0.004). Other classes of flavonoids and total flavonoids were not associated with thyroid cancer risk. Similar associations were found for papillary thyroid cancer.Our findings suggest that dietary intake of different classes of dietary flavonoids may have divergent effects on thyroid cancer risk. More studies are needed to clarify a role of flavonoids in thyroid cancer development. Results from our study suggest a potential nutritional etiology of thyroid cancer.

maybe it only goes for flavonoids in pill form? i cant imagine that natural sources like fruits have such an effect unless u d eat 3 kg of blueberries per day. all fruits veggies and herbs contain flavonoids- Re: Bioflavonoids dc10

This is a reply to # 2,171,693Well, I believe eating too much of natural things can't be good either. But I'm surprised people on here aren't familiar with the subject....

This is a reply to # 2,171,829i dont bother with ascorbic acid anymore.. I dont equate it as real vitamin c. I make myself eat more natural foods like peppers that have natural vitamin c in it.

This is a reply to # 2,171,991ascorbic acid is the active ingredient that is essential for many bodily functions, this has been proven time and time again. The fact YOU dont regard it as vitamin C is irrelevant because your body knows what it is and how to use it.
With the above being said due to its lack of toxicity and its ability to act as a electron donor to the immune system its a very effective way of bolstering the immune system AND making sure your body has the needed nutrient buidling blocks for such things as collagen.
When the body is assaulted by disease/toxins/pathogens it can EASILY deplete the amount of vit C intake from food alone. Countless personal testimonials have shown clogged arteries cleared by use of >6grams of ascorbic acid daily couples with lysine. Good luck eating enough food to get that much vit C daily.

This is a reply to # 2,171,995I disagree with your assessment that ascorbic acid is the active ingredient of vitamin c. And I think perhaps you are misunderstanding me to a degree.
I dont dissuade people from taking ascorbic acid if thats what they choose.. and Im also aware of ascorbic acid's cholesterol-clearing properties in the arteries. (Ive had my dad taking it for about 30 years now).. There are many studies showing many good things from ingesting ascorbic acid.. Ive taken many grams a day of it in the past.
However, none of that requires it to be real vitamin C.
If vitamin C curves scurvy and ascorbic acid cannot curve scurvy, then it makes sense that ascorbic acid is not vitamin C.
It is part of vitamin c. the outer vessel if you will.. but to rely on ascorbic acid exclusively to do the job of vitamin C i think is short-sighted. 20mgs of vitamin C in a white potato may be of much more benefit than 500mg of synthetically made ascorbic acid.
So by all means take ascorbic acid if you wish.. it wont hurt you, and it can help various conditions, of course if the benefits are a result of the acidity then any acid will do and not specifically ascorbic.

This is a reply to # 2,172,020where on earth did you read ascorbic acid wont cure scurvy?
The clogging or arteries is a response to arterial damage. When vit C is not present in ample amounts to properly rebuild damaged collagen the body uses cholesterol as a make shift patch in arterial walls.
The breakdown of collagen is in essence low grade scurvy and is addressed quite well by ascorbic acid.
Do some googling on "Pauling therapy" as well as various first hand reports of success from using it.- Re: Bioflavonoids Stephy79

This is a reply to # 2,172,025Well, Ive read it as well but as with so many things nutritionally related there was no proof, no context and it was just spouted by someone trying to prove their vitamin C product was superior to the far cheaper ascorbic acid.

This is a reply to # 2,172,022I was reading up on the discoverer of vitamin c awhile back because of his quote about taking potassium Iodide and it came up somewhere on the web... Of course he could be wrong..
also found interesting information from dr. royal lee on natural vitamins..

This is a reply to # 2,172,035I wont argue that ideally we want to get the complete nutrient from food sources. However due to the rapid change in society and toxin exposure we now face its simply not practical or even possible to get everything we need from food, especially since our soils are so depleted due to over farming etc.
Yes, I have read the founder of vit C could not cure scurvy with ascorbic acid however that was like 90 years ago.
There are actually multiple forms of ascorbic acid, some worthwhile and some worthless. It very well could be the early founders version of ascorbic acid was not effective but today the manufacturing process has been greatly improved and if you spend some time reading case studies and such on medline (who by the way intentionally withold about 40 years worth of orthomolecular journal entries) you will many cases of scurvy are cured with ascorbic acid.
At the end of the day we have to look beyond nutrients as just simply nutrients because in essence they are. They are electron donors and anything that depletes electrons will also deplete the body of nutrients. With that in mind pathogens and toxins use up electrons at an alarming rate, so fat in fact that they can cause nutrient deficiencies that are nearly impossible to recover from with food alone.
Ascorbic acid is an extremely powerful electron donor and the fact its basically non toxic makes it a great medium for imbuing our bodies with the electrons it needs to control pathogens, toxins and free radicals..

This is a reply to # 2,172,020Prof? Whats Ur take on Selenium ? Or r u simply taking brazil nuts?
And Magnesium? My plant based diet offers me a Daily amount of approx. 500-600 mg per day. But so far i took Magnesium citrite on Top of that.
Zinc is Difficult for me since plant based is generally higher in copper.
What about the High amounts of vit B2 and B3 ? Do u take Those ?

This is a reply to # 2,172,027I used to take big doses of vitamins like B and C, and still do E at times... Theres nothing wrong with them per se.. Its just that its more likely than not that artificial vitamins are incomplete sources(ie theres alot more higher numbered B vitamins than 12, but that seems to be the number everybody stops at)
Minerals might be a little different since theyre inorganic however I prefer taking them naturally when I can for the same reason that in nature they seem to have combinations that seem to assist in assimilation. I do take selenium.. Originally i took some liquid selenium I found at the vitamin shoppe.. then I didnt take any for a month or so.. then recently I bought some selenium from Walmart.. its source is from yeast and I seemed to have noticed a difference with that.. Either that or my body is just responding differently to me taking Iodine over the months??
to be honest I make homemade chocolate milk from raw milk, raw cacao, raw sugar, and blackstrap molasses.. it taste pretty good and its loaded with potassium and magnesium, etc etc...
I think if you find a food source you like that has the nutrients you need youll find that nature has already done the hard part of figuring out how much of each mineral & vitamin is in the food plus the proper ratio of each so that when you consume it your body will benefit much greater than if you went out and bought 25 different supplements and tried to figure it all out.
But again thats just my opinion.- Re: Bioflavonoids Stephy79

This is a reply to # 2,171,995I only took mAx 2 gr ascorbic acid so far and my cholesterol raised from 170 to 220 in 3 months. I Hope its just Plaque/cholesterol getting removed and that the next results get back to "normal" .
I also have a Big intake of Natural vit c though due to my plant based diet. And i take Natural antioxidants such as Hibiskus.- Re: Bioflavonoids Ferventer

This is a reply to # 2,172,023As you have previously been told, when you start taking large doses of vit C the underlying damaged arterial walls get repaired as the collagen gets restored. As that happens the cholesterol lining/stuck to the arterial walls breaks free and is now floating in the blood stream where it can now be seen in lab work.
This is a temporary increase and cholesterol levels should subside as the body metabolizes the extra free cholesterol.- Re: Bioflavonoids Stephy79
